Sausage Stuffed Mushrooms

Who doesn’t love a big platter of stuffed mushrooms?! This popular appetizer has had many variations, but this one is a real tried and true favorite.

The best part is that this homemade appetizer recipe can be prepped ahead of time and frozen before cooking to save you time and effort on those busy days leading up to fast approaching holidays.

These Sausage Stuffed Mushrooms are perfectly poppable and so easy to snack on you won’t even know you’ve eaten the whole batch by yourself!

Key Ingredients

  • mild ground Italian sausage: Or substitute spicy ground Italian sausage for some heat.
  • onion: Any onion will work, diced. We like yellow or white for sautéing.
  • cremini mushrooms: Make sure they are cleaned with the stems cut out and diced.
  • garlic: Finely minced, feel free to add more garlic if you’re a garlic lover.
  • salt and ground black pepper: To taste.
  • dried oregano and dried parsley: A classic combination that compliments the flavors in the sausage and mushrooms.
  • cream cheese: Softened and at room temperature
  • mozzarella cheese: Freshly shredded and divided.
  • parmesan cheese: Freshly grated and also divided.
  • egg: One egg to hold everything together.

How To Make Sausage Stuffed Mushrooms

  1. Begin by preheating the oven to 375°F and spray a large baking pan with nonstick cooking spray. Set the baking pan aside.
  2. In a large skillet, add the Italian sausage and onion and cook over medium heat until it has all turned brown. This should take about 8 minutes.
  3. Add the diced mushroom stems, garlic, salt, oregano, parsley and pepper to the skillet. Stir and cook for about 5 minutes or until the mushrooms have reduced significantly.
  4. Stir in the cream cheese and heat until it is fully melted. Once melted, add ¾ of the mozzarella and ¾ of the parmesan cheese to the skillet and stir and cook until fully combined and melted..
  5. Remove the skillet from heat and let the mixture cool down for about 5 minutes before stirring in the egg.
  6. Once the mixture has slightly cooled, place the mushrooms in the previously set aside baking pan and fill each one with about a tablespoon of filling.
  7. Sprinkle on the remaining mozzarella and parmesan cheese on top and bake for 20 to 25 minutes or until the top of the cheese starts to bubble and turn a dark brown color.
  8. Serve the stuffed mushrooms with a sprinkle freshly chopped parsley as a garnish if desired. Enjoy!

Tips and Variations

  • If you’re having trouble with your mushrooms staying upright while baking, use a mini muffin pan to keep them contained!
  • Chives, rosemary, basil, all would be great additions to the stuffing mixture.
